Fabric Stiffness Tester
Fabric Stiffness Tester is a lab instrument used to measure the stiffness or flexural rigidity of fabric materials. It evaluates how resistant a fabric is to bending, which influences its drape, comfort, and handling characteristics.
Purpose of Fabric Stiffness Tester:
To determine the stiffness of textiles by measuring the bending length and calculating flexural rigidity, often using methods like the Cantilever Test (as per ASTM D1388 or ISO 9073-7).
Working Principle of Fabric Stiffness Tester:
A fabric strip is slid over a horizontal platform until its free end bends under its own weight to a specific angle (usually 41.5°). The length at which this occurs is used to calculate bending length and stiffness.
Main Components of Fabric Stiffness Tester:
– Test Platform: Flat surface for sample movement.
– Graduated Scale: Measures the overhanging length of fabric.
– Angle Indicator: Guides the measurement based on standard deflection angle.
– Fabric Clamp or Guide: Helps place and move the sample smoothly.
Applications of Fabric Stiffness Tester:
– Apparel fabrics (e.g., for comfort and drape analysis)
– Technical textiles (e.g., automotive, medical fabrics)
– Paper, nonwovens, and films
Benefits of Fabric Stiffness Tester:
- Accurate Measurement of Flexibility – Provides reliable data on fabric stiffness, essential for quality control and product development.
- Improves Product Comfort – Helps assess how soft or rigid a fabric will feel in clothing or furnishings.
- Supports Material Selection – Aids designers and engineers in choosing the right fabric for specific applications based on stiffness.
- Quality Assurance – Detects fabric inconsistencies or defects that affect handling or drape.
- Standards Compliance – Enables testing as per international standards like ASTM D1388 and ISO 9073-7 for global product approval.
- Quick and Simple Operation – Delivers fast results with minimal operator training or preparation.
- Applicable to Multiple Materials – Suitable for woven, nonwoven, knitted fabrics, paper, and films.
- Enhances R&D Accuracy – Supports consistent material testing during product innovation and textile finishing.
Features of Fabric Stiffness Tester:
- Graduated Measurement Scale – Precise scale to measure overhang length for accurate stiffness calculation.
- Flat Test Platform – Smooth, level surface ensures consistent and reliable fabric movement.
- Standard Deflection Angle Guide – Built-in 41.5° angle reference for consistent stiffness testing (per ASTM/ISO).
- Manual or Motorized Models – Available in both types for simple or automated operation depending on lab needs.
- Compact Design – Space-saving unit ideal for textile labs and quality control rooms.
- Sample Holder or Clamp – Ensures correct alignment and smooth feeding of fabric strips during testing.
- Durable Construction – Made of corrosion-resistant materials like stainless steel or aluminum for long-term use.
- Compliance with Standards – Supports methods like ASTM D1388, ISO 9073-7 for stiffness testing of fabrics.
- Lightweight and Portable – Easy to move and use in various lab settings.
- Low Maintenance – Simple mechanical parts require minimal servicing.
How to Use Fabric Stiffness Tester (Cantilever Method):
- Prepare the Sample – Cut the fabric into a rectangular strip (e.g., 25 mm × 200 mm), as per standard.
- Place the Sample – Lay the fabric strip flat on the test platform with one end aligned at the zero mark.
- Slide the Fabric – Gently push the fabric forward so it slowly overhangs the platform.
- Watch for Deflection – Stop sliding when the free end of the fabric bends down to the reference angle (typically 41.5°).
- Read the Bending Length – Measure the overhang distance from the scale. This is the bending length (C).
- Calculate Flexural Rigidity
– Use the formula:
G = W × C³
Where:
– G = Flexural rigidity (mg·cm)
– W = Fabric weight per unit area (mg/cm²)
– C = Bending length (cm)
- Repeat for Accuracy – Test both warp and weft directions and average the results for better accuracy.
Tip: Always perform the test in a controlled environment (standard temperature and humidity) for reliable results.
